Nowadays, hyaluronic and polylactic acids are commonly used to fill in wrinkles. The former enjoys greater popularity but the latter offers effects that last definitely longer. Both acids are used differently despite being equally effective. When and why do the first signs of ageing appear and how to deal with them? How do hyaluronic and polylactic acid erase wrinkles?

When and why first wrinkles appear?

First wrinkles appear around 25 and in most cases they are so-called mimic wrinkles. Other types of wrinkles appear as a consequence of hyaluronic acid, collagen and elastin decline. Then, skin starts getting less elastic, it becomes thin, dehydrated and wrinkled. There is more to wrinkle appearance than just the internal factors since UVA and UVB radiation, stressful lifestyle, unhealthy diet, cigarette smoking, improper skin care and even sudden weight loss contribute to wrinkle development.

Ways to deal with wrinkles

Sadly, the process of wrinkle development is inevitable. In order to slow it down, it’s advised to enrich diet with vitamins A, B, C and E that neutralize free radicals. Also, consumption of great amounts of fresh water and application of cream containing high SPF and retinoids are other things to take into consideration to enjoy youthful look for longer. However, when wrinkles appear, aesthetic medicine offers a solution. The most commonly used wrinkle fillers are hyaluronic and polylactic acids.

How does hyaluronic acid deal with wrinkles?

Hyaluronic acid appears in human organism naturally. It’s safe and doesn’t trigger allergic reactions therefore it’s used as a wrinkle filler the most frequently. It bonds water molecules in tissues which translates into better moisturisation, smoothness and suppleness of skin. With age the level of hyaluronic acid slowly decreases and this is how more wrinkles appear on face year by year. Aesthetic medicine doctors smooth the fine lines out by using hyaluronic acid.

What’s interesting, hyaluronic acid may have various cross-linking density, and this quality is selected by a doctor accordingly to the face part the solution is supposed to be injected. For example, in order to reduce crow’s feet and forehead wrinkles, nasolabial folds and marionette lines a hyaluronic acid of low- or medium-density is used. When it comes to needle mesotherapy, hyaluronic acid used for the procedure is made of the small-particle fillers.

The effects of the treatment are visible immediately. Basically, hyaluronic acid reduces wrinkles for 6-8 months. Then, the preparation is absorbed by a human organism completely, therefore the procedure must be carried out again. The lifespan of the effects depend on the density and level of the filler purification. To illustrate, the thicker and more purified the filler is, the longer it remains in skin.

How does polylactic acid deal with wrinkles?

Alike hyaluronic acid, polylactic acid also appears in human skin naturally. Polylactic acid is applied to improve facial skin condition, which means that by injecting it, skin is supposed to win back the lost volume and smoothness. Polylactic acid is appreciated by those who care for natural and long-lasting effect rather than immediate results. Although the effect of filled skin vanishes within a few days since the procedure, all wrinkles and furrows start disappearing slowly in the subsequent months. Polylactic acid, which residues in tissue, keeps stimulating skin to rebuild collagen and create new cells and fibres. This in turn causes tissue growth which leads to wrinkle disappearance. To sum up, thanks to polylactic acid, it’s possible to fight back both the symptoms and causes of aging.
